Answer to Problem 1STP

Correct answer :

The correct answer is option (C) simple sugars.

Explanation of Solution

Explanation/justification for the correct answer :

Option (C) simple sugars. The Carbohydrates begin the journey starting with the intake at the mouth and ending with elimination from the colon. The polysaccharides break down into simple sugars or monosaccharide’s which can be observed by the body. Hence, the correct answer is (C) that is simple sugars

Explanation for incorrect answer :

Option (A) amino acid. Amino acids are a group of organic compounds that contain amine (−NH 2) and carboxyl (−COOH) functional groups, along with a side chain (R group) specific to each amino acid. Hence, the option (A) is not correct.

Option (B) fatty acids. A fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Hence, the option (B) is not correct.

Option (D) starches. Starches are the most important energy source for living organisms. Cereals and root vegetables are a common source of starch. Hence, the option (D) is not correct.
